Sorry for not replying sooner, I totally missed that you sent me a message. At this point, I think you are in better hands with Ivan. I'm not sure what is wrong, and I'm following this thread myself to see how it concludes.

Good luck! You'll get this fixed. Even if you have to drop the engine to check the clutch fork, we can walk you through that, it's not that hard.

Just be aware that it looks like the fork could be cracked, and not broken. That means it could flex under load, but be hard to see without separating the transmission.
